My FT-817 died :-(


 

Tonight, my FT-817 died...

RX on all bands is OK. All used antennas were ok. Now, suddenly,
there is only between 0.5 and 1 Watt coming out of it, only on VHF
and UHF. All other freqs: no show.

What could be the problem? I've tried the resets POWER+F+V/M,
POWER+HOME, POWER+F, POWER+V/M.

I've looked into the alignment menu to see if there were any ratings
at '0', but it looks quite normal, compared to what I've seen in some
postings here (I never went into the alignment menu myself).

I did not do any modification on the rig.

Appreciate any help,

Rene PD1ALD

Rene,

I had a similar problem when the internal rechareable battery voltage
dropped too low. Extenal 12 V was OK. Recharged the internal battery and
the power was OK...

Rene,

If you have an internal batery pack installed, try disconnecting it
from the 817 and run with the 13.8 V DC supply only. If all is well,
you may have a battery problem. Maybe overly discharged.

Even without the battery pack, the power remains low. On HF, no power
comes out (according to the FT-817's power bars: 0 bars!). On the
other hand, my power supply shows about 1 A current.

I checked it with 2 SWR/Power meters. On 20 metres, it gives 500
milliwatt (full power selected on FT-817). External 13,8V power
supply, no batteries inside.

Hi Rene,

This may be a dumb question, but are you sure you have TX power
output selected for 5 W (Operating Function Row 10, A Key)? With the
13.8 V supply, you should have no icon for the TX power out showing.

Yes. I've been using it for about 3 months right now. Best DX (SSB, 5
Watts): Holland - Massachusetts.

You mentioned the CURRENT, at one ampere--What is the VOLTAGE during
transmit???


 

Same thing happened to me about a month ago. But I didn't have any
power on uhf/vhf either. I sent it into yaesu service, and about 3
long weeks later, it came back. On the repair ticket, it said that
they replaced a FET and a resistor. I am assuming that this would be
the power FET.

However, now it works. I did have to correct the power supply voltage
reading, because it displayed the voltage as being exactly 1 volt
higher. Weird.

I'm not sure what caused this all. The only thing that could have
failed in my case would have been my zm2 tuner, as I discovered an
intermittent contact later on. But still, the output should have
rolled off in that case, causing no damage. I don't know. I am just
really careful now.

Good Luck!

My dealer in the Netherlands (Schaart Communications -
) replaced my FT-817 - no questions asked!

So I am back on the air, but very careful!
